In the small city of Strattenburg, there are many lawyers, and though he's only thirteen years old, Theo Boone thinks he's one of them. Theo knows every judge, policeman, court clerk - and a lot about the law. He dreams of being a great trial lawyer, of a life in the courtroom. But Theo finds himself in court much sooner than expected. Because he knows so much - maybe too much - he is suddenly dragged into the middle of a sensational murder trial. A cold-blooded killer is about to go free, and only Theo knows the truth. The stakes are high, but Theo won't stop until justice is served.
